Hey there I'm trying to learn discrete math by myself and I gotta say it really uses a different part of the brain, a part I'm not used to working with. So I don't usually post anything when I'm learning a new thing, I usually think that my question or a version of it at least has been posted already by someone. So this is the first time I created an account.

Thank you in advance, and I hope I can bring as much value to you as you to me.
